A new international study has sent shockwaves through the medical community: as little as three minutes per day of moderate “incidental activity”—everyday movements like taking the stairs, walking briskly, or even performing household chores—could be enough to meaningfully reduce an individual’s risk of cardiovascular events and premature death. The findings, published in the journal Circulation and widely reported in the global press, signal a powerful new approach to heart health, especially for those unable to engage in structured exercise routines (Medical News Today).
The significance of this finding cannot be overstated for Thailand and the world. Cardiovascular disease remains the leading cause of death, responsible for approximately 17.9 million deaths globally each year. In Thailand, non-communicable diseases, particularly heart-related conditions, include increasing rates of heart attack and sudden cardiac arrest, and are now a leading cause of hospitalization and a critical public health priority (World Health Organization). Despite longstanding public health advice that recommends at least 150 minutes of moderate-intensity exercise per week, the reality is that only a small fraction—about 15% to 20%—of middle-aged and older adults consistently meet this standard. For busy Thais whose daily schedules are packed with family duties, work demands, and commutes on congested streets or BTS rides, squeezing in regular gym time can feel nearly impossible.
Researchers led by a professor of physical activity, lifestyle, and population health at the University of Sydney’s Faculty of Medicine and Health, analyzed data from over 24,000 adults in the United Kingdom who were classified as non-exercisers. These individuals, average age 62, wore wrist accelerometers for a week to provide a precise, objective record of their physical activity—regardless of whether it was done for fitness or just as part of day-to-day living. The study stands out for its focus not on traditional, time-specific workouts, but on “incidental physical activity”: climbing stairs, walking a dog, carrying groceries, or mopping the floor—movements woven into life itself.
“Physical inactivity is a major public health issue contributing to 6 million deaths per year globally, and many compromised lives due to disability and chronic disease,” explained the study’s lead researcher. “There is a pressing need to identify feasible ways for people to be physically active. Structured exercise is great, but only a minority do it regularly. So supporting people to develop habits that integrate more incidental activity into their daily routines could be beneficial for long-term heart health” (Medical News Today).
The headline result: engaging in just 4.6 minutes per day of vigorous-intensity incidental activity or about 23.8 minutes of moderate-intensity was associated with significantly lower rates of heart attacks, strokes, and heart-related deaths. Most strikingly, even as little as one minute of highly vigorous activity a day produced nearly the same risk reduction as three to three-and-a-half minutes of moderate-intensity activity. This translated to a 47% reduction in all-cause mortality—meaning fewer deaths from any cause—for those getting around 24 minutes daily of moderate-intensity “incidental” movement, such as fast-paced walking or active chores (Medical News Today).
But what exactly counts as “incidental activity”? Researchers define it as any movement that raises your heart rate and leaves you at least slightly out-of-breath, so long as it occurs outside of traditional workout sessions. This could be as simple as carrying heavy groceries up the stairs at a BTS Skytrain station, cleaning the house in Bangkok’s summer heat, or rushing to catch a bus. In the Thai context, it also includes moving through wet markets, tending to home gardens, walking with elders during early morning temple visits, or taking children to school on foot or by bicycle.
A board-certified interventional cardiologist from an Orange County, California medical centre, interviewed as an outside expert for Medical News Today, praised the study’s pragmatic focus: “People are often discouraged by structured exercises—going to the gym—because they simply don’t have the time or the resources. What this study shows us is that incidental physical activity can have a significant impact on cardiovascular health and allow people to live longer.” He recommended “using the stairs rather than the elevator, walking to local restaurants rather than driving, and being creative about finding opportunities to increase movement throughout the day.”
This advice dovetails with Thailand’s unique urban and rural geography. Many Thai cities, including Bangkok and Chiang Mai, are dense and walkable, with public spaces, traditional wet markets, and reliable (if crowded) public transit. Even for those in rural communities, household tasks such as rice farming, animal care, or temple volunteer work already create opportunities for the kind of moderate-effort bursts endorsed by researchers. For many older Thais, helping grandchildren, running errands by foot, or maintaining family shrines can also contribute to healthier hearts.
Understanding why these brief sparks of physical effort can have such an outsized effect yields further insight. Physical activity increases energy expenditure, enhances circulation, stabilizes blood pressure, supports healthy blood sugar levels, and improves vascular function. Epidemiological reviews from major health bodies like the AHA and WHO consistently tie even brief or irregular physical movement to better long-term outcomes not just for heart disease, but for diabetes, high blood pressure, obesity, and even some cancers. The key, say researchers, is not intensity or duration per se, but frequency—the many “mini-exercises” that accumulate in a normal day can counteract hours spent sitting at a desk, commuting, or taking part in sedentary leisure activities (Wikipedia – Incidental Physical Activity).
The implication for Thai society is profound. Thailand, like much of East and Southeast Asia, is experiencing a rapid ageing of its population. Rates of hypertension, diabetes, and obesity are climbing, a legacy in part of modern lifestyles, dietary change, and long working hours with little time left for recreation. National policy under the Ministry of Public Health has long trumpeted the virtues of “ออกกำลังกาย” (exercise), with initiatives encouraging Thais to walk, run, or cycle for health, and school programs highlighting the importance of sports. But practical barriers—lack of recreation spaces, air pollution, heat waves, crowded transport—too often get in the way.
This new research offers a more flexible and inclusive path: even without formal gym time, Thais of all ages and backgrounds can reap immediate cardiovascular benefits by simply working more movement into daily routines. The effect is measurable with even small adjustments—for example, choosing to walk quickly from the sois to the next BTS station, or picking up the pace while sweeping the yard or carrying water during community volunteer days.
Culturally, incidental activity is deeply woven into the Thai way of life. Elders often walk to the temple before dawn for merit-making, families gather for evening strolls in local parks after the day cools, and many workers still commute in part by foot. But the rise of sedentary work, motorcycle and car commutes, and a gradual shift toward westernized lifestyles threaten these traditions. Maintaining the non-exercise movement that has historically kept Thais healthier—even in the absence of gyms or formal sports—is now more urgent than ever.
Looking to the future, these results suggest that public health messaging in Thailand could pivot from exhorting people to “exercise more” toward nudging everyone to simply add a little more effort, a few moments at a time, to the rhythms of normal life. Healthcare professionals, especially those at public clinics (อนามัย), could give more practical, everyday advice: take the stairs at the hospital, carry bags home from the market rather than using a motorcycle, or sweep the yard vigorously for five minutes each day.
Digital health innovations—like step trackers on smartphones and wearables—can help individuals monitor their incidental movements, encouraging them to see housework, vegetable gardening, or even energetic shopping trips as valid, beneficial exercise. Public health campaigns could also revive and promote traditional community activities, from temple cleaning to participatory urban gardening, on the grounds that every minute counts.
For Thai policymakers, city planners, and employers, the study also recommends investment in environments that make incidental activity easy and safe: pedestrian paths, green spaces, covered walkways shielding from heat and rain, and public transit hubs designed for active commuting. For the elderly and those with disabilities, supports to enable safe movement within the home and neighborhood are equally essential.
What can Thai readers do, starting today? Take small but intentional actions: walk to the neighborhood market, offer to run errands on foot, take an extra flight of stairs, dance while cleaning the house, or help a neighbor with household chores. Parents can encourage children to join in short bursts of activity at home or in the community. Even a few moments of increased intensity can, over days and weeks, produce dramatic improvements in heart health and longevity.
As one Thai proverb says, “Sickness enters by the mouth, and disaster leaves by the feet.” This research lends fresh force to an old wisdom: movement is medicine, and a little bit of everyday effort may truly be the most accessible, affordable route to a healthier, longer life.
